DESK-LAMP.

Specification of Letters Patent.

Patented Mar. 14, 1916.

Application filed. April 5, 1915. Serial No. 19,301.

To all whom it may concern:

Be it known that I, EDWARD H. BINNS, a citizen of the United States,residing at Woodland road, Pittsburgh, in the county of Allegheny andState of Pennsylvania, have invented certain new and useful Improvementsin Desk-Lamps, of which the following is a specification.

This invention relates to desk lamps and more particularly to that type,which is adapted for position upon the top of roll or up-right desks,and in which the deflector overhangs the bed or writing surface thereof.

The primary object of the invention is to construct a lamp, of thischaracter in a substantial and attractive form and at the same timerender it of greater utility and less expensive than those now in use.

The invention consists in the provision of a lamp, having means forcasting the rays of light over the writing bed of the desk and which hasarranged therein a clock and thermometer, the latter being readilyreadable by the occupant of the desk.

A further object of the invention is to completely insulate thethermometer from the heat radiations of the lamp, by means of anon-conductive material disposed between the thermometer and thelighting globe.

lVith this object in View, the invention consists in the construction,combination and arrangement of parts hereinafter clescribed inconnection with the accompanying drawings, and will be more particularlypointed out and ascertained in and by the appended claims.

In the drawings, forming a part of the application, Figure 1 is a frontelevational view of my improved desk lamp. Fig. 2 is a longitudinalvertical section of the lamp, with the incandescent globe and desk inelevation, the latter being broken away.

The lamp as shown, consists of a hollow body portion 1, which may becast or otherwise formed of metal, or other suitable material, andadapted for position on the top or the rail of roll or upright desks.Formed integral with the said body portion 1, and projecting outwardlytherefrom, is the outwardly flaring deflector 2, which extends over aportion of the bed or writing surface of the desk, while the base 3, ofthe body portion rests on the desk top 4, The rear wall 5, of the lampbody proper, 1s thickened at its lower part as at 6, whereby theequilibrium of the lamp is maintained. The deflector 2, is apertured at6, for the reception of the plug 7 into which is screwed theincandescent globe. 8, which latter projects downwardly at an anglewithin the said doflector, and a chain member 9, serves to operate thelamp. The wires 10, connecting the plug 7, with the source of electricalenergy, passes through the hollow central portion of the lamp body, ing11, in the enlarged portion 6, of the rear wall 5 of the lamp body.

The lamp body proper extends upwardly at 12, and the side-walls thereof,are provided with suitable ornamental scrolls 13. A circular opening isformed in the front face of the upper wall of the lamp body and a clock14, is positioned therein, the said clock being wound and set from thedial face thereof. The upper end of the lamp is provided with aninteriorly threaded sleeve 15, and a thermometer 16, formed with athreaded shank 17, is screwed therein, surmounting the said lamp. Thethermometer 16, is of usual construction and positioned so that thetemperature indications are easily read.

An asbestos casing 18, surrounds the clock, and serves to insulate thethermometer 16, from the heat radiated by the lamp, the said insulationcompletely blocking the passage between the upper and lower hollowinterior of the lamp body. The lower hollow portion of the lamp body maybe filled with a suitable non-conductive material, such as asbestos,wool, etc. The base 19, 0f the lamp, is provided with an opening, and asuitable closure :20, seats therein, wherein admittance is given to thehollow interior of the lamp body, for the insertion of thenon-conductive material, or for rewiring the lamp.

It is obvious that with a lamp of this construction, wherein thereflector projects out over thebed of the desk, and the lamp globepositioned at an angle, the light rays will be diffused over the writingsurface or central part of the desk. It is also obvious that thecombination of an overhanging lamp, having a clock and a temperatureindicator therein, a useful as well as an ornamental article is assured,but it is to be understood that changes, variations and modificationscan be resorted to, which may come within the scope of the claimshereinafter appended.

and through the open- Having now described my invention, what I claim asnew, 1s:

1. A lamp comprising a frame having a hollow base portion'and upwardlyextending vspaced vertical rear and front walls, the

front wall provided with an opening, a clock arranged in said opening,an asbestos cas mg surroundlng said clock and completely opening,electric wires arranged in said last named opening and connected to saidglobe, said baseibelng formed with a bottom opening communicating withthe hollow interior thereof, whereby access may be had to the Copies: ofthispatent maybe obtained for five cents each, by addressing thefcommissioner of Patents,

wires and the clock casing, and a closure for said openin r V 2. In adevice of the type set forth, a hollow frame having a frontclower lampcontaining compartment, a rear lower wire receiving compartment forcontaining the feed wires for the lamp, and a top or dome compartment,which latter extends throughthe front wall of the frame and communicateswlth the rear lower compartment, said frame having an opening leadinginto the rear lower compartment, and last named compartment. 7

In testimony whereof I aflix my signature in presence of'two witnesses.
